:-) Whee!
From testing this, two things:
1. Can you please have a look at the following ICE? I suppose you can
reproduce this in your non-checking build by just unconditionally
enabling that df_verify call? Committed to gomp-4_0-branch in r225656:
commit 1aff96b721921f621642c0fab95359453bc01beb

Work around nvptx offloading compiler --enable-checking=yes,df,fold,rtl
breakage
... introduced in r225647.

2. Don't be shy to remove a bunch of XFAILs, in fact all :-) of those
remaining from the test cases that Julian had added in
<http://news.gmane.org/find-root.php?message_id=%3C20150617151515.087aa93e%40octopus%3E>.
Unfortunately, there's also one regressions, but I'm seeing it only on
Nvidia K20 hardware, not on my laptop (but it may well be
hardware-dependent: according to a web search, CUDA error 716 translates
to CUDA_ERROR_MISALIGNED_ADDRESS). Are you reproducing that one, and/or
do you have an idea where it's coming from?
